I should also have said that some breeds are not docked at all, not through laziness but because they don't need it. Many Jacob breeders no longer dock and Northern Shorttailed Sheep such as Soay, Shetland, Hebridean, North Ronaldsay and so on have naturally short tails and must not be docked. Texels are not NST sheep so would naturally have quite long tails. Some dockers get a bit carried away and dock far too short so ewes have no cover for the vulva, which is now seen as a welfare issue. Draggly tails can get daggy and be flystruck, but so can the very shortest of Soay tails - more to do with if dung sticks.
